HOISTING-BUCKET.

To all whom it may concern.'

Be it known that I, ANDREW Wiasiiso, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in l'loisting-Buckets; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in what is herein particularly set forth with reference to the accompanying drawings and pointed out in the claims of this specification, its object being to provide simple, economical, strong, durable and etticient -se arable hoisting buckets of the clam-she species, especial attention being directed to a peculiar suspension of the bucket-sections, the leverage of the same and the' bucket-closing mechanism.

Figure 1 of the drawings represents a sectional view of one of my improved hoisting buckets and is indicated by line 1-1 in the next described showing; Fig. 2, a similar view on the plane indicated by line 2--2 in Figs. 1 and 4, the bucket being open; Fig. 3, a like view of the open bucket indicated by line 3-3 inFigs. 2 and 4; Fig. 4, a plan view of the open bucket partly in horizontal section on the lane indicated by line 4-4 in Fig. 3, and *ig. 5, a horizontal sectional view indicated by line 5 5 in Fig. 3.

Referring by numerals to the drawings, 6 indicates one and 7 the other of the pair of segeniental body-sections of an improved separable hoisting-bucket in accordance with my invention. The body-section 6 of-tlie bucket is provided with a series of arms 8, and the bod -section 7 of said bucket is also provide with a series of arms 9, tive arms bein arms in t e other series. At their outer ends, the several arms are loose on a primary spindle 10 that extends through s ac-` ing sleeves 11 and 12 as well as shac {leplates 13, each of these plates being intermediate of a pair of the sleeves and in connection with a suspended stop-chain 14. Loose on the spindle 10, between arms of the body-sections of the bucket, is shown two pair of sheaves, those of one pair being indicated by the numerals 15, 15', and those of the other pair by the numerals 16, 16. The spindle 10 and parts therewith are held in place by nuts 17 run on the ends of said Specification of Letters Patent.

spindle against outer arms of the body-sections of the bucket, or by other suitable means, said outer arms being riveted direct to the bucket-body sections adjacent to the inner corners of the same, and the other arms of each series are likewise secured to angle-plates 18 siniilarl fastened on the curved portions of sait bucket-body sections. Brace-plates 19 are shown riveted to angle-strips 2O likewise connected to thel outer arms of each bucket-body section and the next adjacent inner arms of the same.

A secondary spindle 21 extends through the inner arms of the bucket-body section 6, and another secondary spindle 22 extends through the inner arms of the other bucketbody 7, these spindles being each held in place by nuts 23 run on the ends thereof against opposing arms of the seiies aforesaid, or by other suitable means. Loose on the spindle 2l is shown a pair of sheaves 24, 24', and loose on the spindle 22 is shown another pair of sheaves 25, 25', all of these paired sheaves being shown as having a diameter greater than that of the sheaves on the'spindle 10. Each of the sheaves 24 and 25 is confined on its spindle between an arm ofl a bucket-body section and a spacingsleeve 26, while each of the sheaves 24 and 25 is confined on its spindle between a pair of said arms.

A head-frame is made up of vertically disposed paired channel bars 28, underlying angle-beams 29, vertically disposed paired fiat-plates 30, horizontal fiat plates 31 and brackets 32. the several arts being riveted together. However the dietail of said headframe may be indefinitely varied. Linkbars 33 are connected at their ends to the paired channel-'bars 28 of the head frame and to paired brackets 34 with which the bucket-body sections are provided, each linkbar beinl interposed between a pair of said channelars and a )air of said brackets on pivot bolts 35, suita ly held in place.

. A. spindle 36 is central of the head-piece parallel to the spindle 10 aforesaid, and said spindle 36 extends through the channel-bars 28 and plates 30 of said head-frame, it being held in place by nuts 37 run on the ends thereof in o position to tlieadjacent channel-bars, or Yby other suitable means. The spindle 36 also extends through spacingcollars 38 and shackle-plates 39 intermediate of such collars, these plates being connected to the upper'ends Yof the stop-chains ,14 aforesaid.

Engaged by the spindle 36, central ofthe head-frame, is the hub of a yoke 4() constituting an equalizer in connection with' bucket-closing cables 41, 42, opposinv guidesheaves 43, 44, looseon said spindle, :andguard-rollers 45, 4G, mounted in said frame to o pose said cables, these sheaves and guari -rollers being arranged between plates 30 of the aforesaid frame. -Slieaves47 are loose on the spindle between channel-bars of the liead'lframe, and hoisting-cables 48 are trained on the sheaves last specified, these sheaves being shown as havlng a greater diameter than those 43, 44 on the same of closing onl the part of the bucket bod spindle.

lVit-h particular reference to Figs. 3- and 4, the cable41, coupled to one end of the yoke 40, extends fdown under the sheave 15, then to the right overA the sheave v25,b then to the left under the vsheave 24, 'thenup under the sheave 15', and fnall upbetween the sheave 44 Iand a 'guard-rol er l46. The cable a 42, con led to'theother end of the yoke-40 exten s down undery thesheave 16'- then tothe leftover the sheave 24\,then1-t0 the right under the sheave 25 then -up under-'the sheavel, and 43and-a guard-rollerl45. fIt\-will'be under stood'- that the cables41 `and 42 pull --in :op-

)osite"directions and that' thestrain thereon is equalized by the yoke 40 to whichitheyare connected, in .order lto effect aiuni'form speed )sections', the hoisting of the bucket beinge ected by the cables 48. i However iti-impractical,

and within the .scopei ofcmy` inventionoas herein claimed, to omit= the hoisting ca 48, as well aso-neef the Ibucket-closing cables and sheaves upon which the same Ais trained, in `which case the remain-ing bucket-closing cable serves.also.asanhoisting eable,-.but in either case provision is had-ffor rapid closing of the open bucket,: the: peculiarsuspension of its body sections being such that powerful leverage is. cxe1ted:the1'eon and ascoOping action ofy the same vobtained u. on theimatcx'ial to be hoisted. The-closed'- ucket being hoistedI to a desiredalt-itude, slacking of the closing-cableor cables will result in-an automatic opening of. saidwbucket: by` gravity of its load .to dump the same.
